A pregnant client with iron-deficiency anemia is prescribed iron supplements. To enhance absorption, she should consume foods high in which vitamin?

Iron absorption is significantly enhanced by the presence of vitamin C. When iron supplements are taken alongside foods rich in vitamin C, such as citrus fruits, tomatoes, and bell peppers, the acidity created by vitamin C helps convert iron to a more easily absorbable form in the intestines. Therefore, for a pregnant client with iron-deficiency anemia, consuming foods high in vitamin C while taking iron supplements is essential to improve the effectiveness of the treatment and increase iron levels more efficiently.

Other vitamins listed do not have the same effect on iron absorption. For instance, vitamin B12 is important for red blood cell formation but does not enhance iron absorption directly. Vitamin D is crucial for calcium metabolism and bone health, while vitamin E primarily serves as an antioxidant and does not play a role in iron absorption. Thus, the choice of vitamin C is crucial for maximizing the benefits of iron supplementation in the context of iron-deficiency anemia during pregnancy.
